Industrial Reverse Osmosis and Deionization Water Quality Conversion Calculator
Convert Conductivity, Resistivity, PPM, and mg/L for Industrial Water Quality
How do you size industrial deionization and reverse osmosis water quality? The Industrial Deionization and Reverse Osmosis Water Quality calculator below shows automatic calculations between conductivity and resistivity. It also calculates resistivity to conductivity as well as to parts per million or milligrams per liter (ppm, mg/L).
Industrial Reverse Osmosis vs. Deionized Water Quality
What is the difference between industrial reverse osmosis (RO) water quality and deionized (DI) water quality?
Typical Conductivity and Resistivity Ranges for RO and DI Water
Generally speaking, reverse osmosis systems will yield around 5-15 Microsiemens [μS] while twin bed or separate bed DI systems yield around 1 Microsiemen [μS]. Mixed bed DI systems can give very high water quality yielding less than 0.06 Microsiemen [μS] or around 18.3 Megohms/cm (million ohms per centimeter).
How Conductivity and Resistivity Are Related
What is the calculation from water conductivity to resistivity? Resistivity is the inverse of conductivity.
